Author's note: Right now this is definitely going to be at least a two-parter.
My name is Joe. This story is about my best friend Rich getting lucky with his mom and older sister during the summer after we graduated high school and how I was fortunate enough to join in.
Since his parents' divorce, Rich lived with his older sister Sherry and his mom. During the fall of our senior year, Rich and I turned 18 and hit the weight room to get in better shape and it paid off as we both packed on extra muscle and it showed. In our senior year of high school, after we turned 18, we would jokingly call Rich "Big Man Dick" because while showering after gym class we noticed he has a huge cock.
At graduation, Rich told me he couldn't believe how great Sherry looked. He said during her year away at college instead of putting on the freshman 15, she lost weight and let her hair grow down past her shoulders. He also told me that while he was getting dressed for graduation she was back to her old tormenting ways. During our junior year, when she was a senior, she'd torture Rich about how scrawny he was. During her semester break (after we turned 18) she heard porn coming from his room and started giving him a hard time about cleaning up. Now, before graduation, she knocked on his door asking if he was starting the festivities with a bang and needed to clean-up.
"We'll find a way to get her," I assured him at graduation.
After graduation we did the usual thing and went party-hopping for a few hours, but we couldn't find one we wanted to stay at. We wound up going back to Rich's house for a swim in his pool and to steal a few beers from the fridge.
We were hanging out poolside, sitting up in lounge chairs, when Sherry came out wearing a lacy red sheer cover-up robe. It was evident she was nude underneath, probably intending to go skinny-dipping. Sherry's 5-foot-8, green eyes, strawberry blonde hair, curves in all the right places, and 40-D breasts.
"Oh my god!" she yelled when she saw us. "What the hell are you two doing here? Shouldn't you be out partying, getting drunk?"
"We couldn't find any parties we liked," I said. "Besides we figured having a beer and swimming was better. Also, I have to say that you look great, especially with the longer hair. The year away has treated you well."
"You really think I look great?" she asked, a little surprised.
"Yes we do," I replied motioning at Rich who nodded in agreement.
I started to rub my hardening cock through my bathing suit and I noticed Rich was doing the same.
"I didn't think I'd do this in front of either of you," she said. "But for a graduation gift, what the hell, happy graduation."
She smiled as she dropped the robe exposing her naked body.
I eased my suit down, exposing my 7-inch cock, continuing to stroke with a slow steady rhythm while staring lustfully at her, trying to let her know I wanted her. Rich had lowered his swim suit and was stroking his big 11-inch a little faster.
She looked at both of us with a big grin and turned to her brother first.
"Richie, slow down, we don't want any clean-ups yet," she laughed. "Just sit back and enjoy the show."
Then she turned to me.
"Joe, look good enough to eat," she said as she walked over licking her lips.
She knelt next to me, grabbed my cock in her hand and lowered her mouth over it.
Her lips felt exquisite as they slid up and down my cock. Her tongue teased me while it was in her mouth. She bobbed her head up and down several times, sucking with just the right touch, before removing me from her mouth and running her tongue up and down the length.
I had one girlfriend try giving me a blowjob earlier in the year, but it was nothing like this. I was in heaven. She started stroking my shaft while taking my balls into her mouth one at a time and then running her tongue over them.
She then climbed onto the lounger, straddling me, rubbing her tits against my chest before leaning in and giving me a kiss. Our lips parted and our tongues danced before she whispered in my ear.
"If we had some condoms out here I'd be riding you until you shot hard, but since we don't you'll have to settle for this."
With that she slid back down my body, wrapped her magnificent breasts around my cock and started rubbing them up and down, giving me a tit fuck.
"Cum for me, give me something to clean up," she cooed.
She stared rubbing them faster and repeated her plea.
"Move your mouth back to my cock," I moaned.
She did and started bobbing up and down on it wildly with just the right amount of pressure and suction between her lips.
"That's it, I'm cumming" I groaned and started to shoot.
She took the first two shots in her mouth before taking me out of her mouth and aiming the rest on her breasts and in her cleavage.
"Fantastic," she smiled at me and got up.
She lifted her breast to her mouth and licked some off. Then she swiped a finger over the cum, scooping it up and then licking it off her finger. She did this several times before smiling at me.
"Delicious," she said.
Then she turned to Rich, with some cum still on them.
"Your turn baby bro," she said as she walked over to him and got on her knees again. "I've been wanting to do this since I saw how big you were last year when you caught me in the shower. But I knew I had to wait until after graduation."
She started to slowly bob up mouth up and down on his shaft but was having trouble getting all of it in her mouth.
"My god, you're huge," she said. "We'll have to change positions for me to deep throat you, taking it all in, come sit on the table."
Rich quickly got up and sat on the edge of one of the tables while Sherry bent over in front of him and went back to work. In this position she was able to go down nearly to the base of his cock, leaving less than an inch, and he was moaning in pleasure.
Also in this position, bent over at the waist, her pussy was on full display and pointing at me.
She shifted from sucking on him to licking and stroking the entire length of his shaft. They were both moaning contentedly and I was stroking myself getting hard at the sight of this.
She started sucking his balls while continuing to stroke him with both hands, causing him to moan louder and put his hands in her hair.
Moments later she started to tit fuck him and I was as hard as a rock.
"We can't have any more messes to cleanup," she laughed before taking him back into her mouth.
At this point I couldn't take it anymore and got up and stood behind her.
